The development, reproduction and longevity of corn aphids Rhopalosiphum padi
(L.), Sitobion avenae (Fabricius) and Metopolophium dirhodum (Walker) were studied at 18, 22, 25,
27.5 and 30ºC. Only nymphs of R. padi survived at 30ºC, but the adult reproductive capacity was very
low. Rhopalosiphum padi performed better than M. dirhodum at all temperatures tested, and better
than S.avenae over the range of 22-27.5ºC. The better performance of R. padi was due to a lower
nymphal mortality, lower developmental and prereproductive times and a higher intrinsic rate of
increase(rm).Sitobion avenae had a higher rm than M. Dirhodum at all temperatures.The most suitable
temperature for population development was =28.5ºC for R. padi, 26.5ºC for S. avenae and 24.5ºC
for M. dirhodum, suggesting the ability of aphid populations to adapt to high temperatures in the
Iberian peninsula. The role of temperature as a key factor in determining aphid population dynamics
in the northeastern Iberian peninsula is discussed
